What are the rovers up to?

Spirit's been getting some nice views of the spot it spent all of 2008 in, "Home Plate north." Here's a panorama composed of five Navcam frames; you can see over at the right the tracks left behind as Spirit descended from the steep slope, including the sad trench left behind its dragging right front wheel. Spirit was parked with that wheel up on top of Home Plate and its middle and back wheels on the slope; it drove off the slope backwards. Thanks to Eduardo Tesheiner for the panorama. (As a reminder, the Navcam is Spirit's binocular navigational camera system located on the mast; the Navcams have a relatively wide field of view, taking in more of the landscape with one shot than the Pancams do, but at lower resolution and monochrome, unlike the color Pancam instrument.)
The view below contains the same images, but Michael Howard has dropped in a 3D model of the Spirit rover, showing where it was parked for the long Martian winter. Coooool.
Although Spirit just got moving for its fourth Martian summer field season, that season is not going to last very long. I've been told by someone on the science team that they only have until October to do science around Home Plate before they'll have to park again on a good north-facing slope from which to wait out the next winter. That's only nine months, folks! Nine months will go by fast.
Meanwhile, Opportunity is motoring along. Here's the latest forward view from sol 1,774, following two 100-meter drives that took it southwest of the spot, "Santorini," where it spent Mars' solar conjunction. I'm intrigued by how cobbly the bedrock in front of Opportunity looks. In other places the bedrock looks like it's been scoured flat; here there's a little topography to that bedrock, under all the dunes.
Opportunity has now traveled about one kilometer south of Victoria crater, while working its way a couple hundred meters to the west. Only another eleven or so kilometers to go to get to the rim of Endeavour -- which lies to the south and a little east. There's still a long, long, long way to go.
